Precision Dosing Using PBPK Modeling

Precision dosing― the right dose, for the right patient, at the right time― is crucial to providing patients with the most efficacious medications with minimal probability of adverse events. One key step towards achieving the delivery of individualized dosing is testing potential dosing regimens in a patient’s ‘virtual twin.’ The other key step is to … Continued

The Next Horizons in Predicting Drug-drug Interactions

Physiologically-based pharmacokinetic (PBPK) modeling has arrived in prime time. This quantitative mechanistic framework, combining physiology with drug information and clinical trial design, has become an integral part of drug discovery and development. PBPK has also gained currency within industry and regulatory agencies. Its applications are numerous, including simulation of pre-clinical, healthy volunteer and special population … Continued

What is Model-based Drug Development Worth?

If you have ever argued, as we have, for the resources and time needed for model-based drug development (MBDD), you have likely encountered that irritating accountant in the room who says, “Sure, this modeling stuff sounds interesting, but how much MONEY will this save us?” My answer: $97M of savings per New Drug Application (NDA). … Continued

Automated Prediction of First-in-man Dosing Using Pre-clinical PK Data

Humans differ from commonly used pre-clinical model organisms (rats, dogs, monkeys) in terms of their biochemistry, physiology, and anatomy. Predicting a drug’s pharmacokinetic (PK) profile in humans using animal PK data must account for these differences. Allometric scaling is used to predict human PK parameters based on animal data. While allometric scaling has been used … Continued
